X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy are used to study the change of the surface layers and chemical state of atoms on galena surface after treatment by high-voltage nanosecond electromagnetic pulses. By XPS the induced structural changes of galena surface layer are associated with alteration of chemical state of sulfur atoms, which conditions the change of...
Using X-ray photoelectron spectroscopy, the authors analyze the change in the surface layer composition and chemical state of atoms of chalcopyrite and sphalerite as a result of treatment by high-power nanosecond electromagnetic pulses. General regular patterns and distinctions of modification of the mineral surface and floatability under high-power pulse treatment are found. The research findings...
